Abstract (en)
The present invention relates to a method for welding at least one foil in a packaging process using a welding assembly (100), comprising the steps of directing the foil (112) into the welding assembly (100), holding the foil (112) in at least one holding point (124,125) of the welding assembly (100), welding the foil (112) in at least one welding point (122,123) of the welding assembly (100), and where a part of the foil (112) is accumulated between the at least one holding point (124,125) and the at least one welding point (122,123) prior to welding the foil (112) in the welding point (122,123). The present invention further relates to a welding assembly (100) employing this method.
